This is a another nicely shot, directed and edited Children's' Film Foundation production, this time very much on location on a Scottish mountain in 1964. The cast, old and young clear chosen as able climbers rather than as amateur actors - to have John Laurie dub one adult was wise decision.
Nice youngsters from around the UK are joined at the two week climbing course by a flash cocky teenage Londoner who arrives in a car with his mates - his character instantly recognised from his foot-wear, fashionable 50 years ago: "Winkle-pickers" - shoes with long very pointed toes.
He of course ignores all undoubtedly good advice and climbs a forbidden peak without ropes with the inevitable - in CFF terms -- results.
50 years on, with the intervening arrival of parkour, Alain Robert the Frenchman climbing skyscrapers just with the aid of talcum power and sticky tape, and the online antics of people dangling from one arm from the tallest aerial masts, I wonder what the current generation would make of this film with its good safety advice?
